I want to find the number of times 'x' is present in my file, so I submit
%s/x//gn and get the correct answer.
How can I capture the resultant count into a variable using vimscript on the command-line?
The following solution was hinted at by an answer below:
:let cnt=0 :g/x/let cnt=cnt+1 :echo cnt
cnt is made to store the total number of lines in the buffer that have an
x, not how many
xs there are in the whole file.
So, the original question still stands.
